CeeNU Oral Warnings
Lomustine may cause serious blood disorders (decreased bone marrow function leading to low number of white blood cells/platelets and anemia). It can lower your body's ability to fight an infection and increase your risk of bleeding. These side effects usually occur 4-6 weeks after your dose. Higher doses and more doses increase the chance of these side effects.
Seek immediate medical attention if you develop symptoms of infection (fever, chills, persistent sore throat) or unusually easy bruising/ bleeding. (See also Side Effects section.)
Your doctor will monitor you and perform blood tests weekly for at least 6 weeks after each dose. Your dose and any further treatment will be based on your blood tests. You will have to wait at least 6 weeks between doses.
CeeNU Oral Uses
Take this medication by mouth as a single dose as directed by your doctor. (See also Warning section.) Your dose may consist of 2 or more different strengths/colors of capsules. Taking this medication on an empty stomach with a full glass of water may decrease nausea and vomiting. Unless your doctor instructs you otherwise, drink plenty of fluids to avoid a serious loss of body water (dehydration).
The dosage is based on your medical condition, other treatments (e.g., radiation, chemotherapy), body size, and response to therapy (e.g., side effects such as low white blood cell count).
Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and the risk of serious side effects may be increased.
Wear rubber or latex gloves when you handle the capsules.
CeeNU Oral Side Effects
Nausea, vomiting, loss of appetite, diarrhea, and mouth/lip sores may occur. Nausea and vomiting usually last for less than 24 hours, though loss of appetite can last for several days. Nausea and vomiting can be quite severe. In some cases, your doctor may prescribe medication to prevent/treat nausea and vomiting. Changes in diet such as eating several small meals or limiting activity may help decrease some of these effects. If these effects persist or worsen, notify your doctor or pharmacist promptly.
Temporary hair loss may occur. Normal hair growth should return after treatment has ended.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. (See also Warning section.)
